Improvement in btjtter-tttb



finilrd ,gieten DAVID LOWN, `OF PGHKEEPSIE, NEW YORK.

Letters Patent No. 92,734, elated July 20, 1869.

Adorf- The Schedine referred to in these Letters 'Patent and making part of the same.

To all whom lt may concern Be it known that I, DAVID LowN,"of Poughkeepsie,'in the county-of Dutchess, and State of New York, have invented a new and useful Improvement in Express Butter-Tubs; and Ido hereby declare that the following is a full, clear, and eXact description .of the same, reference being hadto the accompanying drawings, and to the letters of reference marked thereon, making a part' of this specification.

This-invention relates to a new and useful improvement in butter-tubs in which `butter is conveyed to market or to any distributing depot, from which it is sold-,to wholesale merchants or to consumers, and the tubs, when empty, returned to the producers.

' These tubs are sometimes termed return buttertubs, and are designed to be apermanent articlerof manufacture.

'The object of my invention is te obtain a secure fastening for the lid, and one which will not project above the upper surface -of the same, and interfere with the placing of the tubs one upon another, and which will also readily admit of the lid being fastened and unfastened with facility, and canse the under surface of the latter to lit snugly upon the'butter, so as to exclude a passage of air over the upper surface of the same, and `also prevent the admission 0f water (rain) within the tub.

In the accompanying sheet of drawings- Figure 1 is a plan or top view of my invention.l

. Figure 2, a side view of the upper portion of the same, partly in section.

Figures 3 and 4, detached perspective views of the two parts comprising the fastening. j

Similar letters of reference indicate corresponding .parts in the several figures.

' Teenable those skilled in the art to fully understand and construct my invention, I will proceed t0 describe it.

AV represents thel body Aof .the (tub, which may be made of staves, bound together by hoops, the usual Inode of construction, or it may be made in any other suitable manner.

B @represent the two parts which comprise the fastening, and D representsr the lid of the tub.

This lid is constructed of one or more pieces, and to its under surface there is secured, by screws, nails, or otherwise, a circular projecting'batten, a, which is just equalin diameter to the inner'diameter ofthe upper end of the tub, so that whelr'the lid is secured on the tub, the bat-ten will snugly lit -i-into the upper pa'rt 'of the same. y

The lid D is equal in diameter to the exterior of the upper end of the tub, and hence laps entirely over the upper surfaces of -the staves. l

The hatten a, like the lid; may beicomposedof one or more pieces, and the latter are secured to the under Yeide of D, so that the grain of the wood of 'a will be at right angles to that of D.

` The two parts, B C, which comprise the fastening,

are made of cast-iron, malleable or otherwise, their shape being Vplainly shown in figs. 3 and 4, and they are secured, by screws or otherwise, to the outer side of the tub, and in such position that the upper surfaces of said parts will be flush with the upper surface of the lid D, when the latter is secured on the tub.

The upper endsof the parts B C are -cast with. an

out wardly-proj ectin g lip, designated respectively by b b',

and these lips are designed to serve ashandles in raising and moving the tub from place'to'place.

In addition to this outwardly-projecting lip b of the part B, there is au inwardly-projecting lip, c, which is not more than half the width of b, and extends from the centre of the latter. (See fig. 1.)

The lip c extends a short distance over the top of the lid D, and a recess, rl, is made in the lid to receive 1 it, so that the upper surface of the lips' b c may bev ush with the upper surface of the lid when the latter It has an outwardly-projecting lip b', as before de scribed, but this lip is cast with a central recess, e, which is about the same width as the lip c.

This recess e receives a latch, f, which is securedin position by a pintle, g, extending entirely through the lip b', the outer end of said latchextending to the outer edge of b', and its inner edge, extending inward so as to project over the upper surface of the lid D, about the same distance as the lip c projects .over it, the lid being provided with a recess, h, to receive the inner part of the latch, so that the upper surface of the inner part of the -latch will, when 'the lid is secured on the tub,be flush with the upper surface of the latter.`

` The latch f is allowed to swing freely on its pintle g, and its outer -end or part is prevented from casually. descending, and its inner end from casually rising, by a pivoted button, h', which, when turned to a vertical position, has its upper end directly underneath and in contact with the under side of the outer part of the latch.

This swinging latch,'it will of course-.be seen, is a necessity, as it admits of the lid being removed when required.

This4 is done by shoving the button h to one side, so -that the inner-end of the latch may be raised,

The button h' is pivoted at its lower end to the lower portion of the part C of the fastening, as shown in figs. 2 and 4. v

This fastening maybe constructed and applied at a very small cost. It is extremely durable, having no parts which are liable to get out of repair, and no projections extending above the surface ofthe lid to in,-

terfere with a. series of tubs being placed one upon another to rest in a firm position.

Having thus described my invention,

What I claim. as new, and desire to secure by Letters Patent, is

The fastening for the lid D, composed of the two parts B C, one of said parts, B, having two fixed lips, b c, the formor of which, b, projects outward, and the other, c, inwerdQver the lid, the part- C also having :t

fixed outwardly-projectingslip, b', and zt latch, f, with a, pivoted button, h', underneath; the 'above-named parts being arranged and combined with a butter-tub and its lid, substantially as herein shown and described.
